Just found this thread. I've got two DL580 G7's with E7-4870's. I'm currently mining with 30 GPU's on standard mobo's. Never could get GPU's to work in these. Is it still profitable to set these up and eliminate the "small" rigs? I am currently running ZEC, but would switch out to something else if profitability is there. Would definitely want to swap CPU's to 8837's.

It all depends i would say. The DL580's are power-hoggers. What is nice is H/s per $ on the initial costs, but running them worth profit requires cheap electricity since there is a lot of overhead power drain on these systems. If your electricity is not cheap, i wouldn't mind moving my cards from the standard mobos. Perhaps you could take 1-2 PSU's from them switch to, since they are 90-95% platinum rated. Then you need breakout boards.

Tried reading through the whole thread...but it's really long Cheesy

Has anyone found any "cheap" 4U+ rack mount systems that can run 4-7 cards internally?


The HP DL580 G7 can be found for less than 500$: https://h20195.www2.hpe.com/v2/getpdf.aspx/c04123267.pdf?ver=19+

I have over 50x 550s.

12 x each rig.

Each does around 480h/s for 42w

What motherboard and brand of gpus?

That is a problem with the HP server series like the G7 which are a bit old so HiveOS maybe does not have the best support for them. I will also blame HP or any other old server like Dell as I have tested HiveOS with 12 RX 580 cards in ASUS B250 Pro Mining and they worked out of the box perfectly without problems with a great hashrate of 360 Mhs.

The strong Xeon processors are good to mine Bytecoin or Monero.

Actually HiveOS and the HP's work GREAT.  Currently have 2 running 9 cards each.

It's HiveOS and the Dell R815's that DOESN'T and that's just a NIC driver issue.

Guess i have to give HiveOS a second chance then Wink

The Dell R815s that I got are running rock solid.

Hard to justify the price at this point, though, IMHO -- unless you get a sweet deal.

Well... I have to take that back a bit now.

My power flickered last night thus turning off all my hardware. Came in, turned all the Dells back on... started XMR-STAK on them all & walked off.

Noticed my pool hash-rate never returned to how it was... every one of my R815s is now ~400 H/S slower than they were before the power flickered (1600 H/S vs. 2000 H/S).

I've tried re-booting and even re-compiling XMR-STAK... seems to be permanent ?!

Any ideas ?

Im really shocked you have not invested in UPS for your systems man.. i ordered 25 x of the CyberPower CP1500AVRLCD, i got them refurbished off ebay, the guy only had 25 left, so i contacted him to ask if i could buy all 25 at a better rate and he sold them to me for $88 each, but at that time was spring time sales, so i was able to get 20% using the emailed spring code i had sitting in reserves. I have one of these 1500 units on every 6 and less GPU rig i have running right now...

I was about to pull the trigger before all the coins fell off a cliff in value, hah...

I am pricing out a full set of UPS units, though, through some distributors... since I'll need 100+ of them. Gonna just have to suck it up I suppose!

Try to source them refurbished or on ebay with bad batteries. I bought 3 from ebay that were server based UPS that just needed new batteries and i picked them up off amazon for a few dollars each, i even went to my local thrift stores and picked up a handful of them for a few dollars and half of them even worked, just needed fresh batteries. The ones i got from local thrift stores i built custom lithium batteries from 18650 cells, i have been collecting thousands of them over time because i was planning to build a DIY tesla powerwall with them along with build battery packs for my Catrike bicycle that i converted to electric assist, i get them free from thrift stores, hardware stores from the recycle bin just ask the store managers, and colleges. The most i got from thrift stores because when someone donates a laptio they cant resell it, so it gets scrapped and disassembled and they pay for someone to take the batteries away.

This is some of the batteries i got last month from going around and asking politely from many locations and picking up some from locations that told me they would place them to the side for me...


Here are some cells im still slowly testing out, i bought 4 tester/chargers units a while back that allows me to test 16 cells at a time, so its only time to test them, i put them on the test and forget about them really and come back when i remember about them, write the capacity on the side of the cell and move on, i store them in bins based on the capacity so my wall cells i assemble have the highest capacity cells. I have probably close to 40,000 cells assembled in my diy powerwall to date that ive never purchased...




"I have probably close to 40,000 cells assembled in my diy powerwall to date that ive never purchased... "

Thats seriously impressive man!

Under Linux, I have 6 Nvidia cards working.  Not sure what is up with the Proliant G7 series.  I have tried a DL360, DL380 and the DL580 and none of these will boot with more than 4 GPUs installed.  Windows will lock up at loading screen.

Slap a USB stick with HiveOS on it and 6 get recognized easily.

I have a ML350P G8 that has taken 6 GPUs in windows easily.  

Edit* Make that 9 1060s in one 580 in HiveOS.

I hit a wall at 9 cards on the 580 also, using SMOS. Spent countless hours getting 9 cards to work. In one way i love the HP servers, H/s on cryptonight is a bonus but as a gpu-mining platform they look good on paper but is in my experience not fun maintaining. Did anyone try to run Windows 10 on the 580 with success?

Will there be support for https://github.com/fireice-uk/xmr-stak so i can utilize my xeon cpus and dualmine gpu+cpu on cryptonight?
I know this can be achieved by installing from terminal, but i would be nice to have gui support.
Thanks

Thanks for answering. I use SMOS and Cast-XMR is not currently supported.
Claymore 11.3 gives me the best speed so far at ~785H/s using stock settings
xmrig-amd-v2.6.0-beta1 with --opencl-launch 896x4 gives ~710H/s

My cards are clocked at 1280/2000.

Any ideas?

Try with --opencl-launch 896x8

I tried 896x4 and 1024x4, and the later one gives ~740H/s


I mentioned to try 896x8 not 896x4 (or was that a typo?)

Sorry, my bad. How many threads can you run per gpu?

Another thing...

Same miner, (Claymore 11.3) same settings, same kind of cards:
System #1 - 8 cards, avg ~740 H/s
System #2 - 2 cards, avg ~929 H/s

What is bottlenecking system #1?

Finally  i got  the  command line for  Intensity with XMRig-AMD

Code:
--opencl-platform 0 --opencl-devices 0,1,2,3,4,5 --opencl-launch 985x8 --opencl-affinity 0 -o stratum+tcp://[POOL.PORT] -u [WALLET] -p x --donate-level=1 --print-time=5

getting 750 H/s per card, but  RX5xx can reach around 850-900 H/s



If you got reach 850 H/s+  with XMRig , share your config - command line! , thanks!

I don't use xmrig but try --opencl-launch 896x8.

Yeah,  with XMRig i got 750 H/s per RX... but finally with Claymore 11.3 i am getting 860-870 H/s per card.   thanks

Would you mind sharing your settings with Claymore 11.3? Im stuck at ~785H/s with my Rx570 (they do 29mh/s+ with eth)

Yes,  i am getting 870-880 H/s with RX570,  with Claymore 11.3 (SMOS) , in Windows,  you can reach 900-1000 H/s with Cast-XMR.

Code:
-xpool stratum+tcp://[POOL:PORT] -pow7 1 -xwal [WALLET] -xpsw x

Looks great Spinx!
Thanks!


Nice system.

I am trying Hive OS on my DL580 G7 with 4x E7-4830's and 4x GTX 750. It is up and running but something must be wrong with my configuration for the CPUs. I am getting some affinity errors on a few CPU cores and those cores only produce 11 H/s instead of the 33 H/s on cores where affinity works. I have disabled hyper-threading in the BIOS so the 32 cores shown are real CPU cores.

Could you post the CPU configuration that you used with Hive OS. Hopefully that will fix my problem.

Also is the rack that the DL580 and GPUs are mounted in a commercial rack or home made?

If home made can you provide assembly instructions.

Thanks

Reason i left hiveOS was that i never got it stable. Constant freeze and reboots, but it has a lot more features, on paper its far superior to SMOS.

I dont have the configs left i think, but please have a look at my post here on settings for E7-8837 with xmr-stak: https://bitcointalk.org/index.php?topic=1955358.msg28646698#msg28646698

The rack inside the server cabinet is custom built, bought the alu-profiles from my local hardware shop for ~75 euro, a bit expensive but very easy to build. I will look for a drawing, i only made one on paper Smiley

Any idea how to get 11 gpus working? I seriously wasted like all nights in a week to try to solve this. Changing hardware and waiting for multiple 15 min reboots is not something i like to do again.

Great discussions and info in this thread!

Just wanted to share my DL580 G7 build, wanted to run 11 cards, but settled with 9 after hours and hours of struggle.

Mining etherium at ~ 255MH/s. Ran Cryptonight at 1650H/s with 4x E7-8837, but stopped since i switch to SimpleMiner from hiveOS (had to prioritize gpu stability).

This is interesting...

"With 20 KH/s hashrate for Cryptonight and 40 KH/s for Cryptonight-lite at just 60 Watts of power usage any GPU feels out of date already, even AMDís VEGA GPUs with just about 2 KH/s are not interesting for mining these algorithms anymore. So Monero (XMR) is going to become the next major ASIC only coin with the many Cryptonight-based alternatives following when the Giant-N miners start hitting the market, unless of course they fork to another algorithm."

That's a link to a url that shows the image. You need to use an image link (ends in .jpg, .gif, .png, etc).

sundownz posts have pictures showing and they do not have any extension.

See here: https://bitcointalk.org/index.php?topic=1955358.msg31588057#msg31588057

The link to one of his pictures is: https://ibb.co/jsWe57

You can put that link in a browser and see the picture and you can do the same with my picture link.

So the answer is not the extension but must be something else.



He used this code, note the [img] tags and the url pointing directly to the .jpg -file. Remove the asterix (*) from the code below to use.

So i have a problem using Claymore, my GPU #7 (in the miner screen) is getting lots of rejected shares, i think this single card cant handle the tighter timings (started with 1500 strap on all RX570 cards).



This makes me want to re-flash the default rom on this card, but this is where i get confused. The gpu #id's in claymore doesnt lign up with the id's in using lspci | grep VGA or atiflash -i.
I first tried to flash atiflash -p 7 but that turned out to be gpu #3 in claymore... (verified this with the lowered hashrate). Cant take a chance again since i have mixed Hynix/Samsung cards. How can i correctly identify what card to flash?

Glad to see you guys got the G7s up and running. I've been scouring ebay trying to find a better deal than those G7s for mining and haven't been able to find anything.

I posted a little guide / blurb for how to run a 240V 30A outlet for residences in the USA.. If anyone needs more power...

https://bitcointalk.org/index.php?topic=2772135.msg28578662#msg28578662


What i have not solved yet is running 12 gpus in my G7. Im fairly sure how to solve the electricity, except how i solve common ground the best way, since i need to take 1-2 psu's and mount them externally to be able to fit the pci-e breakout boards. With normal ATX-psu's i have add2psu-adapters solving this, but now im not really confident in whats the best solution is?

And also, does Windows Server support 12 gpu's?

Put the GPUs on pci-e expansion boards. Power the expansion boards from the 2x psus you leave attached to the G7. Take other 2 PSUs, put breakout boards on them and run it to the GPU cards 6/8pin port. CPU Mining will kill 1kW (depending on cpus) from the 2x PSUs you leave in the unit. You should still be able to optionally stick a couple cards in the system itself.

I don't know about windows, I'd never run windows for any miner.

I'm not sure what you mean by a common ground. I'd just plug all the PSUs into the same PDU. Here's my PDU:
https://www.amazon.com/gp/product/B0013HY9E2/ref=ox_sc_act_title_5?smid=ASF0S1GFIHF5V&psc=1


Thanks a lot for this clarification. I tried booting up with SMOS with 2 cards mounted directly on the motherboard, but SMOS would only detect 1. What OS would you runt with 12 AMD RX cards in my G7?

Are they RX vegas or 5xx 4xx? If latter, just use linux, if former, uh, you might as well save yourself the trouble and commit yourself to an asylum now. I don't think vegas would work in this thing? I didn't check what PCI-E rev it has, but I can't imagine it's more than 2.1.

Make sure your bios is updated to latest. Play with the port configuration. Different pci-e lanes should be attached to different cpus, and I don't know what that configuration looks like. I would just run everything on risers.

I normally run centos, just because that's what I use all day on prod servers at work. debian, ubuntu, centos, etc, any of them should work fine. You'll need to check on driver availability as they only usually support a couple distros. I remember having to reinstall to ubuntu from debian or vice versa because amd only had drivers for one and not the other.

More recently I've been looking into engineering samples on ebay. Intel ES abound, but AMD ES is limited. I've gone through profitability calculations on all these chips and most of the ES are sitting at like 5-6 months on cryptonight. I think someone has already been picking up these ES chips to mine on them.

Other than that, with scalable coming out, I would be looking for cheaper v2s and v3s to start hitting ebay and refurb dealers. I've seen a couple instances of v2 and v3 on ebay where power usage is 1.2-1.3x, hashrate 0.9-1.1x and cost around 0.5x (at current prices) of vegas. Most of these units have some number of pci-e slots on them (usually only a couple). But it would allow you to stick a couple gpus on each unit.


They are all RX570, im going to try with HiveOS now as i didn't have success with SMOS and its seems to be a lot of hassle to get both drivers and multiple cards to work properly on Windows. I have risers for all cards, as i can use built in graphics for monitoring. Sound like a good idea, one i get my G7 going smooth i will look for another project!

Response from PICO distributor:

Oh dear. I can immediately see what is wrong here.

In image 2 the *output* of the picoPSU is connected to the motherboard AUXPWR1 Ė which is also an output!

According to the manual for your TB250-BTC  this is an auxiliary power connection (to give additional power to) graphics cards. i.e. power goes into motherboard through the ATX connector, and comes out here.

Hopefully this hasnít damaged the motherboard. It has obviously damaged the picoPSU.

FWIW the output you connected is to power a hard drive or similar device.


Was that just an old 160w pico?  Think you need one of the newer 200-250w pico's to be able to power anything more than a hard drive and normal motherboard.  I think that molex connection sucked too much juice and just smoked the low watt pico.

I also smoked a 160w pico when i used the single molex to power a usb pci-e riser (rx560 with no 6pin). Fingers crossed that mobo survived!
